UFC on FX 6, which also served as the final of “The Ultimate Fighter: The Smashes,” takes place Dec. 15 at Gold Coast Convention and Exhibition Centre in Broadbeach, Gold Coast, Australia. The event’s main card airs live on FX (on Dec. 14 in the U.S. due to the time difference) following prelims on FUEL TV.

Mendez vs. Penner likely will be part of the prelims.

Mendez, a California-based fighter and onetime Strikeforce competitor, recently announced his UFC deal. Mendez turned pro in 2008 and has racked up a 7-0-1 record (with one no-contest). While most of his fights have come with regional promotions, he made an appearance with Strikeforce in late 2011. Mendez edged former WEC fighter Fernando Gonzalez (17-9 at the time) via split decision with a late rally in his lone Strikeforce appearance.

Penner, meanwhile, is a veteran of the Canadian fight circuit who signed with the UFC earlier this year after winning eight straight fights, six via stoppage. However, in his promotional debut, he suffered a first-round TKO loss to Anthony Perosh at UFC on FX 2. He then was slated to fight Tom DeBlass at UFC on FUEL TV 4 but ultimately scratched from the July card with an undisclosed injury.
